Sentinel-5P Atmospheric Monitoring Satellite Rides into Orbit atop Converted Ballistic Missile
October 13, 2017

A Russian ICBM-turned-space-launch-vehicle lifted off from a remote Cosmodrome north of Moscow on Friday, boosting into orbit a satellite joining the world's largest environmental monitoring constellation. Joining five Sentinel satellites already in orbit, the Sentinel-5P mission will serve as an important gapfiller, ensuring a long-term record of atmospheric monitoring remains uninterrupted as older satellites retire and new, operational missions under Sentinel are still in development.

The three-stage Rockot/Briz-KM launch vehicle blasted off from Site 133/3 at the Plesetsk Cosmodrome at precisely 9:27:44 UTC on Friday to deliver the 820-Kilogram satellite to its precise drop-off point over 800 Kilometers above the planet. Rockot's two converted ballistic missile stages fired for just over five minutes before the Briz-KM upper stage took over for a pair of engine burns to lift Sentinel-5P into a Sun Synchronous Orbit. Loaded springs pushed the satellite off into orbit 79 minutes after liftoff and first signals received from the spacecraft indicated it was healthy, the European Space Agency said.

Europe's Copernicus program is a multi-billion-Euro effort to create a satellite constellation and ground architecture capable of collecting a comprehensive set of Earth observation parameters and turning them into relevant, usable data for scientists and policy-makers. For that, the program operates a variety of instruments including high-resolution multi-spectral cameras, radars and specialized sensors, providing a complete picture of Earth's land surface, ocean states and atmospheric parameters.

The Copernicus Program's global surveys are used by policy-makers, maritime operators, scientists, meteorologists and resource managers. Taking the pulse of an ever-changing planet, the Copernicus satellite constellation is expected to finish deployment by 2020. Copernicus is operated by the European Commission, ESA and EUMETSAT and represents Europe's single most expensive space project with a cost of $10 billion through deployment of the fully operational constellation.

The Sentinel satellite fleet began deployment in April 2014 when the Sentinel-1A Synthetic Aperture Radar Satellite took flight from French Guiana, setting out to deliver day-and-night radar imaging for land and ocean services, operating in two-satellite constellation with Sentinel-1B launched in 2016 to obtain a high revisit rate.

Outfitted with high-resolution optical imagers, the Sentinel-2 pair launched in June 2015 and March 2017 delivers information on land surface parameters, vegetation, soil and water cover, inland water bodies and coastal areas. The Sentinel-3 series, the first of which launched in January 2016, hosts four specialized sensors taking land and ocean temperature measurements and delivering topographical data.

Sentinel-4 and 5 are upcoming hosted payloads flying on the next-generation weather satellites operated by EUMETSAT with Sentinel-4 aiming for Geostationary Orbit and Sentinel-5 deployed on the MetOp Second Generation satellites, both dedicated to monitoring Earth's atmosphere. Since they are still several years from launch, the European Commission decided in 2008 it would be advantageous to deploy a gapfiller in order to ensure a continued atmospheric monitoring capability after the end of ESA's Envisat mission in 2012 and the approaching end of mission for NASA's Aura satellite launched in 2004.

Sentinel-5P, formally the Sentinel-5 Precursor, is designed to fill this gap via seven years of operation for the collection of global atmospheric composition at high resolution and with daily coverage of the entire planet. The satellite was built by Airbus Defence and Space in the UK and hosts the Dutch TROPOMI instrument, the Tropospheric Monitoring Instrument – an array of four imaging spectrometers with wide angle optics to capture spectral data in the ultraviolet, visible and infrared wavelengths across a 2,600-Kilometer ground swath at a spatial resolution of seven Kilometers.

The 220-Kilogram TROPOMI makes use of Differential Optical Absorption Spectrometry, measuring the backscattered solar light from Earth's atmosphere to detect the characteristic absorption lines of atmospheric constituents down to trace amounts. Its high spatial resolution will enable Sentinel-5P to study methane and CO2 hot spots of natural and man-made origin and also examine sinks for greenhouse gases, among a range of other atmospheric constituents. In total, the operational data products delivered by the mission will provide concentration maps for 19 chemical species, clouds and suspended aerosols.

Friday's launch marked the beginning of the end for Russia's venerable Rockot Booster that debuted as a space launch vehicle in 1990 and has since launched 31 times on missions for the Russian Ministry of Defence and international customers. Rockot employs surplus missile stages from the UR-100N Intercontinental Ballistic Missile that are topped by a Briz-KM upper stage to allow the vehicle to inject up to two metric tons into Low Earth Orbit.

Like a number of launch vehicles originating from the former Eastern Bloc, Rockot has recently fallen victim to the conflict between Russia and the Ukraine over the annexation of Crimea, a fate shared with the Zenit and Dnepr programs as Ukrainian-built launch vehicle components were no longer being exported to Russia. In case of Rockot, critical flight control equipment was only delivered after European officials got involved to negotiate the delivery of the hardware for the Sentinel-5P mission which ended up slipping repeatedly due to these import problems as well as other technical issues with the Rockot booster.

The launch of Sentinel-5P probably was Rockot's penultimate flight with the launch of ESA's Sentinel-3B in 2018 most likely putting a close to Rockot's career as the vehicle makes room for newer rockets like the Soyuz 2-1v and Angara 1.2.

After a long road to launch, Sentinel-5P finally took its place atop Rockot last Saturday and Russian technicians filled the two stages of the launcher with nearly 85 metric tons of toxic hydrazine and nitrogen tetroxide propellants on Wednesday. Countdown operations were initiated seven hours ahead of T-0 when teams at the European Space Operations Center began calling up the ground stations involved in the mission while the spacecraft team in Plesetsk started a number of checkouts and reconfigurations to put Sentinel-5P into its launch configuration.

The Russian State Commission provided final clearance for launch and Rockot went through final Guidance, Navigation and Control checks inside T-3 hours with Site 133/3 cleared for liftoff one hour before launch. The 29-meter tall Rockot – still partially hidden in its above-ground launch container – was revealed just ten minutes before launch when its Mobile Service Tower retracted for liftoff.

Rockot entered the irreversible steps of its final countdown sequence at T-3 minutes with the pressurization of tanks, opening of fuel valves, the transfer to internal power and the activation of the Guidance Platform. Clocks hit zero at 9:27:30 UTC when final guidance system initialization started.

Rockot ignited its four first stage engines and lifted off at precisely 9:27:44.025 UTC, rising from its launch tube, initially guided by rails. Thundering off, the 107-metric ton Rockot completed a short vertical ascent before starting to pitch and roll to align itself with the planned ascent path to the north west, immediately disappearing into low-hanging clouds over Russia's primary military launch base

Спойлер

.Ascending with a total thrust of 191 metric-ton-force, Rockot burned some 600 Kilograms of propellant per second as it powered away from Earth with three RD-0233 engines and one RD-0234, quickly moving past the speed of sound. The launch vehicle encountered Maximum Dynamic Pressure 50 seconds after lifting off, passing 11 Kilometers in altitude and traveling at 570 meters per second.

At T+2 minutes and 16 seconds, the four-chamber RD-0236 vernier engine of the second stage was ignited and soared up to full thrust of 1,600 Kilogram-force as its exhaust was directed through four hatches on the first stage. Shutdown of the first stage came at T+2:19 and was followed split-seconds later by the separation, assisted by four retrorockets that pushed the first stage away to clear the way for the second stage to ignite its main engine.

With the first stage headed to a crash landing in the Barents Sea, Stage 2 fired up its RD-0235 main engine, outputting a thrust of 24,500 Kilogram-force for a burn of just under three minutes to lift the vehicle out of the atmosphere. The four gimbaling nozzles of the vernier engine delivered vehicle control during second stage flight.


Image: ESA/ATG medialab

When the stack reached an altitude of 120 Kilometers, it was safe to jettison the protective payload fairing and expose the Sentinel-5P satellite as aerodynamic forces could no longer harm the delicate payload.

Rockot's job was done at T+5 minutes and 19 seconds when it shut down its second stage and separated the Briz-KM upper stage to finish the orbital injection. Briz-KM initially ignited its four 392-Newton vernier engines for propellant settling prior to firing up its S5.98 main engine on a burn of nine minutes to lift the satellite into a Parking Orbit.

Overall, Briz-KM is 2.6 meters long and launches with a propellant load of nearly 5 metric tons, also using Unsymmetrical Dimethylhydrazine and Nitrogen Tetroxide like the first two stages of Rockot. The 2,000 Kilogram-force S5.98 engine was still firing when the launcher headed out of communications range, aiming for an orbit of 183 by 799 Kilometers.

Achieving orbit, Briz-KM was programmed to passively coast to the high-point of its parking orbit and then fire its S5.98 engine for under one minute to circularize the orbit and deliver Sentinel-5P close to its operational Sun Synchronous Orbit 824 Kilometers in altitude, inclined 97.74 degrees


First Signals from Sentinel-5P – Photo: ESA Webcast

Separation of the satellite at 10:46 UTC set in motion a pre-programmed series of steps aboard the vehicle to deploy its three solar arrays, reduce body rates and power up its transmitter. Initial signals from Sentinel-5P were received through the Kiruna Ground Station in Sweden, confirming the satellite was healthy and in its planned orbit.

Over the next three days, the satellite will go through its Launch & Early Operations Phase to finish detailed checkouts and transition into a safe configuration for its commissioning phase – taking several months as lengthy decontamination is required by the highly sensitive satellite prior to taking its first look at Earth's atmosphere.

The next launch for the Copernicus Program will be Sentinel-3B to complete the two-satellite Sentinel-3 constellation.

Sentinel-5P: satellite in excellent health
16 October 2017

Launched last week, Europe's Sentinel-5P satellite – the first Copernicus mission dedicated to monitoring the air we breathe – is in excellent health.

Спойлер

The 820 kg satellite was lofted into orbit from the Plesetsk Cosmodrome in northern Russia last Friday on a Rockot.

The satellite will use its state-of-the-art Tropomi instrument to monitor our atmosphere, mapping a multitude of gases that affect the air we breathe, our climate and human health.

After separating from the upper stage at an orbital speed of around 27 000 km/h, Sentinel opened its three solar panels and began communicating with Earth.

The first signal was received 93 min after launch as it passed over the Kiruna station in northern Sweden.

Critical early days

Contact meant that engineers at ESA's mission control in Darmstadt, Germany, could assume control of the satellite, and begin working around the clock to check its condition and start setting it up it for routine flight.

he satellite is on solar power, its navigation and communication systems are operating as expected and it is fully functional after its raucous ride into space.

"Sentinel-5P is in excellent health and we were a little ahead of schedule in the timeline for the first three days," says spacecraft operations manager Daniel Mesples.

"That meant we could reduce our 24 hours-a-day schedule a little earlier than planned and declare that the initial phase was complete by Saturday evening.

"As of today, we're back to working daytime hours. Everything is going very well."

Preparing for the sniffing phase

The good news means the satellite is ready for the next crucial phase: commissioning the Tropomi atmosphere sensor over the next six months.

 Once in service, it will map the entire planet every day for Europe's Copernicus Atmosphere Monitoring Service air quality forecasts and for decision-making.

It is the first Copernicus mission dedicated to monitoring our atmosphere. It follows a fleet of five other Sentinels already in orbit and delivering a wealth of information about our planet.

The Sentinels make up the core of the space component of the EU's Copernicus environmental monitoring network.

An EU flagship space initiative, Copernicus provides timely operational information on the world's land surfaces, oceans and atmosphere to support environmental and security policymaking, and meet the needs of citizens and service providers.

[свернуть]

 "The satellite completed its initial critical orbital activities in just about 33 hours, a record, and this time there were no surprises," says Paolo Ferri, head of mission operations at ESA.

"This is a testament to the quality of the satellite builders and the expertise of the mission control team, mixed with the necessary bit of luck.

"Given the complexity of spaceflight and the factors that can't be fully predicted, we can't always count on this, but we are happy when it does happen."

Time to pack up

Following the excitement of launching Sentinel-5P on Friday 13 October, the weekend was much quieter here in Plesetsk.

Time has been mainly spent retrieving equipment from the MIK cleanroom and from the 'under table room', packing up and preparing to go home.

Спойлер

For the team at ESA's European Spacecraft Operations Centre it has been a different story as they were busy with Sentinel-5P's launch and early orbit phase, which they achieved in record time!

So the satellite is now ready to begin the commissioning phase.

The displays offer a snapshot of the temperatures of the Tropomi radiant cooler door inside and outside. The door will remain closed until 7 November. The warm values are temperatures inside the instrument (which need to stay at about 37°C until we open the door. The -61°C and -64°C indicate the temperatures outside the cooler door.

At the European Spacecraft Operations Centre (ESOC) with the launch and early orbit phase over, the team move into the commissioning phase, which will last six months. This will culminate in the in orbit commissioning review, IOCR, after which the satellite will begin its life delivering information on air quality for Europe's Copernicus programme.

Yesterday though, the X-band link, which relays all the scientific data, was used for the first time and worked perfectly. Also  Sentinel-5p was added to the wall of fame by being added to the scoreboard.

Ракетные обломки угрожают жизни северных народов
25 октября 20:24        
                                                                      
 Европейское космическое агентство 13 октября запустило на орбиту очередной спутник, однако лидеры инуитов в Канаде и Гренландии выступали против этого, заявляя о риске загрязнения важной для них арктической зоны космическим мусором.

 Большая часть высокотоксичного ракетного топлива сгорает во время запуска, но остатки летят вниз. Таким образом, когда вторая ступень ракеты отделилась и упала на Землю, она могла содержать до тонны несгоревшего гидразинового топлива, которое было «намеренно выброшено» в Северную водную полынью (North Water Polynya) в заливе Баффина, между Нунавутом и Гренландией.

 Полынья представляет собой зону открытой воды, окруженную морским льдом. Это место обитания арктических видов, таких как нарвалы и тюлени, и один из самых биологически продуктивных районов Арктики. Инуиты — коренные народы Северной Америки — добывают там пищу, поэтому для них он имеет важное продовольственное значение.

 До запуска бывший премьер-министр Гренландии Куупик Клейст назвал неприемлемым попадание потенциально опасного ракетного топлива в Полынью. Согласно ранее опубликованному исследованию, с 2002 года по меньшей мере 10 подобных запусков с северных берегов Норвегии и России привели к попаданию ступеней ракет в этот район или в Баренцево море.

 В соответствии со статьей 29 Декларации ООН о правах коренных народов, государства должны следить за тем, чтобы опасные материалы не попадали на территории коренных народов без их согласия. Однако запуск на позапрошлой неделе, как и другие до него, не были согласованы с инуитами.

 Что будет, если что-то пойдет не так?

 Гидразин — чрезвычайно токсичное химическое вещество, которое редко используется космическими программами из-за его прямой угрозы. Ученым мало известно о последствиях длительного воздействия гидразина на человека и поведении этого вещества в арктической морской среде.

 Гидразин использовался при запуске спутника для мониторинга атмосферы, осуществленном ЕКА на позапрошлой неделе с российского космодрома «Плесецк». Однако ЕКА отрицает, что ракетная ступень может представлять какую-либо угрозу для арктической окружающей среды. Вместе с тем Майкл Байерс, канадский исследователь по вопросам глобальной политики и международного права в Университете Британской Колумбии, подчеркнул, что в настоящее время нет информации о том, сколько неиспользованного гидразина попадает в воду.

 Теоретически, ракетный мусор должен сгореть при повторном входе в атмосферу Земли, не достигнув поверхности. Но что будет, если что-то пойдет не так?

 Правительство Нунавута заявило, что вероятность попадания топлива на Землю остается низкой. Однако риск в любой степени неприемлем, и циркумполярный совет инуитов (ICC) потребовал от космических агентств использовать менее токсичные альтернативы.

 Более двух третей их домохозяйств не имеют надежного доступа к пище. Как неоднократно указывали инуиты, любой риск, связанный с окружающей средой в Арктике, может повлиять на их продовольственную безопасность, питание и здоровье, а также на средства к существованию и культуру. Бывший глава ICC Окалик Эгезияк сказал о предыдущих запусках: «Земля, куда упадет ракета, это не пустыня... Это наш дом».

"До тонны" это они зубы крокодилам нарисовали. Не более пары сотен килограмм скорее на момент отделения. И  все сгорает.
2-я ступень как-никак.

 Природные богатства Полыньи принадлежат всему человечеству, а не только инуитам.  Инуиты обязаны частью добываемых богатств делится с другими народами Земли.  Неплохо бы обложить их небольшим необременительным налогом в пользу постоянно голодающиж и мучающихся от жары африканских детей. Вон какую рыбину вытащили и собираются съёсть, а как же белые медведи и касатки? Нехорошо!
